The present study arises for the necessity of improving the quality of the dry sawed wood get from the process of artificial
drying, specifically the bound quality to the cracks, warps, moisture dispersion and tensions generated at the end of the
process, which are harmful for the later transformation processes that it possesses the industry of the furniture pieces.
The effect of the drying is studied on the different levels of retention of salts of CCA (cooper, Chromium, Arsenic) in sawed
wood of Pinus radiata, like the dimensional variation likewise in the pieces that were part of the study.
The methodology consisted on subjecting the wood to a process of conventional artificial drying, evaluating 2 drying programs,
previously the wood had been subjected to a pre -drie process arriving to a moisture content of 8%, for then to be impregnated
at two different retention levels (4 and 6 Kg/m3), leaving a period of fixation of 10 days.
To evaluate the quality of the drying programs one carries out by means of analysis of Anova, looking for the difference significant
minimum among the two programs, having as comparison wood without impregnating, with 4 and 6 kg/m3 of salts of CCA.
As the retention levels go increasing the defects they are increased in both programs, specifically you increment the long
of crack and the twist like main defect.
The Second program present more defects generating only the 28.42% of the defects, in comparison with the first program that
was be a level of defects of 70.73%, having a high significant the quantity of cracks and high tensions, in what refers at
the time of drying, the program Nº 2 increment the time of drying in 7,3 hours but, for ende a lengthening of the drying
cycle, however the decrease of the defects generates a gain for the company, since the desclasification level is diminished.
